What you can do

Save & Unpack Mac DMG File Data on any Windows System

Use this free DMG extractor to save and unpack Mac DMG file data on any Windows system. No Mac required — validate and prepare DMG disk images in your browser, then unpack with 7-Zip or similar on Windows.

Extract Data from Read Only and Compressed DMG Files

Extract data from read-only and compressed DMG files. The tool supports standard UDIF DMG format and validates read-only and compressed disk images so you know which files are ready to unpack on Windows.

Option to Add Multiple DMG Files One After the Other

Add multiple DMG files one after the other. Build a list of disk images, then run extract/validate on all of them at once. Remove individual files from the list if needed before processing.

Provides Different Search Options to Find Data in Disk Image File

Search options to find data in your disk image list: search by file name or by status (success/fail). Filter the results table after completion so you can quickly locate specific DMG files or see only succeeded or failed items.

Unpack DMG Emails Along with the Associated Attachments

When your DMG contains email files (e.g. .eml, .msg) and attachments, unpack the disk image with 7-Zip or your preferred extractor on Windows to get emails along with their associated attachments in one place.

Display Both Success and Fail Count Report After Completion

After processing, the tool displays a completion report with both success count and fail count. See at a glance how many DMG files were valid and how many failed, plus a detailed table with status and notes for each file.

FAQ

Frequently Asked Questions

Q1. Can I use this DMG extractor on Windows?
Yes. This tool runs in your browser, so you can use it on any Windows system to add and validate Mac DMG files. To actually unpack (extract) the contents to folders and files, use 7-Zip or another Windows-compatible extractor that supports DMG.
Q2. Does it work with read-only and compressed DMG files?
The tool validates standard UDIF DMG format, including read-only and compressed disk images. If the file is recognized as a valid DMG, it is reported as success and can be unpacked with desktop tools. Encrypted or non-UDIF variants may show as failed.
Q3. Can I add multiple DMG files?
Yes. You can add multiple DMG files one after the other. Each time you add files, they are appended to the list. You can remove individual files from the list, then run extract/validate on all remaining files.
Q4. What search options are there?
After the completion report, you can search by file name (to find a specific DMG in the list) or by status (e.g. show only success or only failed) to quickly find data in the disk image file list.
Q5. How do I unpack DMG emails and attachments?
Once you have validated your DMG, open it with 7-Zip (or another DMG-capable tool) on Windows and extract to a folder. If the DMG contains email files (.eml, .msg) and attachments, they will be unpacked together into that folder.
Q6. What does the success/fail report show?
The report shows a success count and a fail count after processing. Each file is listed with its name, size, status (Success or Failed), and a short note. Success means the file was recognized as a valid DMG format.
